One channel is used for management of I/O dat a, the other for directly data transfer between storage devices and clients. By using the difference between commands and data, the server burden can be release d greatly. The Stochastic Petri-net model of its file request processing was es tablished and the effect of the improved performance was analyzed.
Second, file request was transferred to super-computer monitored and controlled machine tool by NC system, and the file folder and catalog was searched according to the file request of response machine tool to implement listed files in mutual operation.
This paper studies a fuzzy logic rule base for adaptive striping of files across multiple disks,and the rule base is based on an analytical model of disk contention that includes disk physical parameters and file request sizes; based on auto classifying of access patterns and real-time monitored data of file system.
The main objective of the tool is to optimally allocate the video files to different storage media based on the system parameters and the video file request probability distribution.
In the first one, all the processes share real core; in the second, processes having issued a file request lose their memory space until the I/O is performed.
NR-SS system was designed with heterogeneous channel s between sever and storage devices. One channel is used for management of I/O dat a, the other for directly data transfer between storage devices and clients. By using the difference between commands and data, the server burden can be release d greatly. The Stochastic Petri-net model of its file request processing was es tablished and the effect of the improved performance was analyzed.
In this paper, we proposed a new remote access method based on HTTP protocol. By sending the file information through HTML form, the program on the server side can store these information into the database. At the same time, the sever can response the users file request, and delete the file from the dabatase adaptively.
There are two methods for listed files in mutual operation between super-computer and NC system. First, the file request was transferred to NC system by super-computer, after the request was received by the system, and it searched file, and file was returned through list form mode. The advisable files were selected by super-computer to transfer to NC system, and then, the file was transferred back to super-computer to save by NC system. Second, file r...
